John Perry's book Knowledge, Possibility, and Consciousness is a lucid and engaging defense of a physicalist view of consciousness against various anti-physicalist arguments. In what follows, I will address Perry's responses to the three main anti-physicalist arguments he discusses: the zombie argument , the knowledge argument , and the modal argument.

A number of philosophers have recently argued that consciousness properties are identical with some set of physical or functional properties and that we can explain away the frequently felt puzzlement about this claim as a delusion or confusion generated by our different ways of apprehending or thinking about consciousness. This paper examines David Papineau’s influential version of this view. According to Papineau, the difference between our “phenomenal” and “material” concepts of consciousness produces an instinctive but erroneous intuition that these concepts (...) can’t co-refer. I claim that this account fails. To begin with, it is arguable that we are mystified about physicalism even when the account predicts that we shouldn’t be. Further, and worse, the account predicts that an “intuition of distinctness” will arise in cases where it clearly does not. In conclusion, I make some remarks on the prospects for, constraints on, and alternatives to, a successful defence of the claim. (shrink)

We review existing strategies for bringing modal intuitions to bear against materialist theories of consciousness, and then propose a new strategy. Unlike existing strategies, which assume that imagination (suitably constrained) is a good guide to modal truth, the strategy proposed here makes no assumptions about the probative value of imagination. However, unlike traditional modal arguments, the argument developed here delivers only the conclusion that we should not believe that materialism is true, not that we should believe that it is false.

This paper compares and contrasts two conceivability arguments: the zombie argument (ZA) against physicalism, and the perfect actor argument (AA) against behaviourism. I start the paper by assuming that the arguments are of the same kind, and that AA is sound. On the basis of these two assumptions I criticize the most common philosophical suggestions in the literature today about what is wrong with ZA, and what is right in it. I end the paper by suggesting that the comparison between (...) the two arguments makes plausible an epistemic response to ZA according to which the conceivability of a zombie - that is, someone identical to me in all physical respects but different in some phenomenal respect - is being confused with the conceivability of something else, i.e. someone identical to me in physical respects that are epistemically available, but different in some phenomenal respect.

This is the introductory essay to the collection of essays: 'Acquaintance: New Essays' (eds. Knowles & Raleigh, forthcoming, OUP). In this essay I provide some historical background to the concept of acquaintance. I examine various Russellian theses about acquaintance that contemporary acquaintance theorists may wish to reject. I consider a number of questions that acquaintance theorists face. I provide a survey of current debates in philosophy where acquaintance has recently been invoked. And I also provide brief summaries of the other (...) essays in this volume. (shrink)

Over the past fifty years the philosophy of language and mind has been dominated by a nondescriptivist approach to content and reference. This book attempts to recast and systematize that approach by offering an indexical model in terms of mental files. According to Recanati, we refer through mental files, the function of which is to store information derived through certain types of contextual relation the subject bears to objects in his or her environment. The reference of a file is determined (...) relationally, not satisfactionally, so a file is not to be equated to the body of (mis-)information it contains. Mental files are the mental equivalent of singular terms, and the reference of linguistic expressions is inherited from that of the files we associate with them. On this approach, mental files, the vehicles of singular thought, do all the work of so-called 'modes of presentation' in Fregean and neo-Russellian theories. (shrink)

Frank Jackson’s famous Knowledge Argument moves from the premise that complete physical knowledge about experiences is not complete knowledge about experiences to the falsity of physicalism. Some physicalists (e.g., John Perry) have countered by arguing that what Jackson’s Mary, the perfect scientist who acquires all physical knowledge about experiencing red while being locked in a monochromatic room, lacks before experiencing red is merely a piece of recognitional knowledge of an identity, and that since lacking a piece of recognitional knowledge of (...) an identity does not entail lacking any pieces of knowledge of worldly facts, physicalism is safe. I will argue that what Mary lacks in her room is not merely a piece of recognitional knowledge of an identity and that some physicalists have failed to see this because of a failure to appreciate that Mary’s epistemic progress when she first experiences red has two different stages. While the second epistemic stage can perhaps be plausibly considered as acquiring merely a piece of recognitional knowledge of an identity, there is good reason to think that the first epistemic stage cannot be thus considered.

The question “What is the nature of experience?” is of perennial philosophical concern. It deals not only with the nature of experience qua experience, but additionally with related questions about the experiencing subject and that which is experienced. In other words, to speak of the philosophical problem of experience, one must also address questions about mind, world, and the various relations that link them together. Both William James and Kitarō Nishida were deeply concerned with these issues. Their shared notion of (...) “pure experience” is the conceptual cornerstone of their attempt to deal with the philosophical problem of experience. This dissertation is an analysis of “pure experience” and its relevance to several issues in contemporary hilosophy of mind. Drawing upon James’s and Nishida’s “pure experience”, I argue both for a sensorimotor-based, “extended” conception of consciousness and a bodily skills-based account of moral psychology. (shrink)

Both a priori physicalism and a posteriori physicalism combine a metaphysical and an epistemological thesis. They agree about the metaphysical thesis: our world is wholly physical. Most agree that this requires everything that there is must be necessitated by the sort of truths described by physics. If we call the conjunction of the basic truths of physics P, all physicalists agree that P entails for any truth Q. Where they disagree is whether or not this entailment can be known a (...) priori. The a priori physicalist says it can, the a posteriori physicalist says it cannot. Though a posteriori physicalism is probably the dominant view, it is really a surprising and somewhat unlikely stance. In this article, the nature of the view is discussed, and two arguments are presented that should cause us to look again at the potential of a priori physicalism. (shrink)

This paper presents the hypothesis that the representational repertoire underpinning our ability to process the lexical items of a natural language can be modeled as a system of mental files. To start, I clarify the basic phenomena that an account of lexical knowledge should be able to elucidate. Then, I propose to evaluate whether the mental files theory can be brought to bear on an account of the representational format of lexical knowledge by modeling mental words as recognitional files.

Knowledge of what it’s like to have perceptual experiences, e.g. of what it’s like to see red or taste Turkish coffee, is phenomenal knowledge; and it is knowledge the substantial or significant nature of which is widely assumed to pose a challenge for physicalism. Call this the New Challenge to physicalism. The goal of this paper is to take a closer look at the New Challenge. I show, first, that it is surprisingly difficult to spell out clearly and neutrally what (...) the New Challenge is in fact urging the physicalist to explain. What initially look like plausible or promising ways of making sense of it turn out to be either question begging or insufficient to generate a challenge to physicalism at all. I go on to suggest that what the New Challenge may be asking the physicalist to explain may be the fact that we come to token certain higher-order judgments about the significance of phenomenal knowledge. I end with a discussion of the implications of this interpretation of the New Challenge—which turns out to be as much a challenge for the anti-physicalist as it is for the physicalist. (shrink)

What is the relationship between pain and the body? I claim that pain is best explained as a type of personal experience and the bodily response during pain is best explained in terms of a type of mechanical neurophysiologic operation. I apply the radical philosophy of identity theory from philosophy of mind to the relationship between the personal experience of pain and specific neurophysiologic mechanism and argue that the relationship between them is best explained as one of type identity. Specifically, (...) pain is a specific type of personal experience identical to a specific type of allostatic stress response comprised of interdependent nervous, endocrine and immune mechanical operations.

It is common parlance among philosophers who inquire into the nature of consciousness to speak of there being something it is like for the subject of a mental state to be in it. The popularity of the ‘what-it-is-like’ phrase stems, in part, from the assumption that it enables us to distinguish, in an intuitive and illuminating way, between conscious and unconscious mental states: conscious mental states, unlike unconscious mental states, are such that there is something it is like for their (...) subjects to be in them. The ‘what-it-is-like’ phrase, however, has not gone unopposed; some very clever philosophers have vigorously disputed it. Peter Hacker, for example, has argued that the phrase should be abandoned because it is ungrammatical, and Paul Snowdon has argued that it should be abandoned because the propositions expressed by its usage are either trivial or false. This paper mounts a case for the claim that neither of these conclusions is warranted. Against Hacker, it is argued that the arguments he produces for the ungrammaticality of the phrase are unpersuasive, and against Snowdon it is argued that he fails to consider a plausible and independently motivated interpretation of the phrase, and that, on this interpretation, the propositions expressed by its usage are non-trivially true.

In this paper it is argued that existing ‘self-representational’ theories of phenomenal consciousness do not adequately address the problem of higher-order misrepresentation. Drawing a page from the phenomenal concepts literature, a novel self-representational account is introduced that does. This is the quotational theory of phenomenal consciousness, according to which the higher-order component of a conscious state is constituted by the quotational component of a quotational phenomenal concept. According to the quotational theory of consciousness, phenomenal concepts help to account for the (...) very nature of phenomenally conscious states. Thus, the paper integrates two largely distinct explanatory projects in the field of consciousness studies: (i) the project of explaining how we think about our phenomenally conscious states, and (ii) the project of explaining what phenomenally conscious states are in the first place. (shrink)

It's a common idea in philosophy that we possess a peculiar kind of "phenomenal concept" by which we can think about our conscious states in "inner" and "direct" ways, as for example, when I attend to the way a current pain feels and think about this feeling as such. Such phenomenal ways of thinking figure in a variety of theoretical contexts. The bulk of this article discusses their use in a certain strategy – the phenomenal concept strategy – for defending (...) the physicalist view that conscious states are reducible to brain states. It also considers, more briefly, how phenomenal concepts have been used to defend dualism about consciousness, and how they have been used to explain our special access to our consciousness. It concludes with a discussion about whether, and in what more precise sense of the term, we at all possess "phenomenal concepts" of our conscious states. (shrink)

It has long been widely agreed that some concepts can be possessed only by those who have undergone a certain type of phenomenal experience. Orthodoxy among contemporary philosophers of mind has it that these phenomenal concepts provide the key to understanding many disputes between physicalists and their opponents, and in particular offer an explanation of Mary’s predicament in the situation exploited by Frank Jackson's knowledge argument. I reject the orthodox view; I deny that there are phenomenal concepts. My arguments exploit (...) the sort of considerations that are typically used to motivate externalism about mental content. Although physicalists often appeal to phenomenal concepts to defend their view against the knowledge argument, I argue that this is a mistake. The knowledge argument depends on phenomenal concepts; if there are no phenomenal concepts, then the knowledge argument fails. (shrink)

Identity theories are those that hold that 'sensations are brain processes'. In particular, they hold that mental/psychological state kinds are identical to brain/neuroscientific state kinds. In this paper, I isolate and explain some of the key features of contemporary identity theories. They are then contrasted with the main live alternatives by means of considering the two most important lines of objection to identity theories.

The aim of this paper is to defend a prototype B-theory answer to McTaggart’s Puzzle about Time. Smart hopes to solve the issue by pointing to the “anthropocentricity” of temporal A-notions. There is one important problem: explaining Prior cases (for instance being relieved that a painful experience is over ) in B-theoretic terms. First, it is argued that the problem is how to explain the nature of the subject’s tensed belief in Prior cases; the essential indexicality of the concept ‘ (...) now ’. Then it is suggested that Smart could utilize Burge’s framework for dealing with de re beliefs and a way of formalizing tensed beliefs is proposed. The last section of the paper deals with the exact role of the formalized indexical element. If these three steps are worked out, we might have an explanation of the facts involved in Prior cases without mentioning any A-facts. Hence an important problem to a Smart-influenced B-theory is solved, and McTaggart’s Puzzle answered in an adequate manner. (shrink)

During the last two decades, several different anti-physicalist arguments based on an epistemic or conceptual gap between the phenomenal and the physical have been proposed. The most promising physicalist line of defense in the face of these arguments – the Phenomenal Concept Strategy – is based on the idea that these epistemic and conceptual gaps can be explained by appeal to the nature of phenomenal concepts rather than the nature of non-physical phenomenal properties. Phenomenal concepts, on this proposal, involve unique (...) cognitive mechanisms, but none that could not be fully physically implemented. David Chalmers has recently presented a Master Argument to show that the Phenomenal Concept Strategy – not just this or that version of it, but any version of it – fails. Chalmers argues that the phenomenal concepts posited by such theories are either not physicalistically explicable, or they cannot explain our epistemic situation with regard to qualia. I argue that it is his Master Argument that fails. My claim is his argument does not provide any new reasons to reject the Phenomenal Concept Strategy. I also argue that, although the Phenomenal Concept Strategy is successful in showing that the physicalist is not rationally compelled to give up physicalism in the light of the anti-physicalist arguments, the anti-physicalist is not rationally compelled to give up the anti-physicalist argument in the light of the Phenomenal Concept Strategy either.

Given Kripke’s semantic views, a statement, such as ‘Water is H 2 O’, expresses a necessary a posteriori truth. Yet it seems that we can conceive that this statement could have been false; hence, it appears that we can conceive impossible states of affairs as holding. Kripke used a de dicto strategy and a de re strategy to address three illusions that arise with respect to necessary a posteriori truths: (1) the illusion that a statement such as ‘Water is H (...) 2 O’ possibly expresses a falsehood, (2) the illusion that conceivability can fail to latch on to a genuine metaphysical possibility, and (3) the illusion that one can access a real metaphysical possibility by conceiving that water is not H 2 O. In this paper I argue that while Kripke’s de dicto strategy dispels (1), his strategies do not enable him to dispel (2) and (3). (shrink)

Kripke's argument against the identity theory in the philosophy of mind runs as follows. Suppose some psychophysical identity statement S is true. Then S would seem to be contingent at least in the sense that S seems possibly false. And given that seeming contingency entails genuine contingency when it comes to such statements S is contingent. But S is necessary if true. So S is false. This entry considers responses to each of the three premises. It turns out that each (...) response does not fully withstand scrutiny, and so Kripke's conclusion is hard to resist. Section 1 lays out Kripke's argument, and Sections 2 to 4 then discuss responses to each of the three premises respectively. (shrink)

A celebrated problem for representationalist theories of phenomenal character is that, given externalism about content, these theories lead to externalism about phenomenal character. While externalism about content is widely accepted, externalism about phenomenal character strikes many philosophers as wildly implausible. Even if internally identical individuals could have different thoughts, it is said, if one of them has a headache, or a tingly sensation, so must the other. In this paper, I argue that recent work on phenomenal concepts reveals that, contrary (...) to appearances, this standard conjunction of externalism about content and internalism about phenomenal character is ultimately untenable on other models of phenomenal character as well, including even “qualia realism.” This would be significant for a number of reasons. The first is patent: it would undermine a primary objection to representationalism. The fact that representationalism is incompatible with the conjunction would be no serious problem for representationalism if no other plausible model of phenomenal character is compatible with it. The second is that the many philosophers who embrace the conjunction would be forced to abandon one of the two views; externalism would be true either of both content and phenomenal character, or of neither. Likewise, those philosophers who have taken a stance on only one of the two internalism/externalism debates would have to be seen as thereby committed to a particular stance on the other. The third reason stems from the fact that qualia realism typically goes hand in hand with internalism about phenomenal character. To the extent that it does, my argument would reveal that qualia realism is itself in tension with externalism about content. This would perhaps be the most surprising result of all. (shrink)

What follows for the ability hypothesis reply to the knowledge argument if knowledge-how is just a form of knowledge-that? The obvious answer is that the ability hypothesis is false. For the ability hypothesis says that, when Mary sees red for the first time, Frank Jackson’s super-scientist gains only knowledge-how and not knowledge-that. In this paper I argue that this obvious answer is wrong: a version of the ability hypothesis might be true even if knowledge-how is a form of knowledge-that. To (...) establish this conclusion I utilize Jason Stanley and Timothy Williamson’s well-known account of knowledge-how as “simply a species of propositional knowledge” . I demonstrate that we can restate the core claims of the ability hypothesis – that Mary only gains new knowledge-how and not knowledge-that – within their account of knowledge-how as a species of knowledge-that. I examine the implications of this result for both critics and proponents of the ability hypothesis. (shrink)

Boran Berčić, in the second volume of his recent book "Filozofija" , offers two responses to David Chalmers’s conceivability or modal argument against physicalism. This latter argument aims at showing that zombies, our physical duplicates who lack consciousness, are metaphysically possible, given that they are conceivable. Berčić’s first response is based on the principle of the uniformity of nature that states that causes of a certain type will always cause effects of the same type. His second response is based on (...) the assumption that the basic statements of physicalism in philosophy of mind are or should be contingently true. I argue that if Berčić’s first defence is aimed at the conceivability of zombies, it is unsatisfactory. Moreover, I argue that a quite similar argument, offered by John Perry in his book "Knowledge, Possibility and Consciousness" , is afflicted by a similar problem. Nevertheless, under a more plausible interpretation, Berčić’s argument might be taken to attack the metaphysical possibility of zombies. This version of the argument might be effective and has the merit to point out a so far overlooked link between the discussion of the Chalmers’s conceivability arguments against physicalism and the modal strength of causal links and natural laws. Then, I argue that Berčić’s second defence of physicalism, which cannot be combined consistently with his first one, in any case, should not be formulated in the terms of contingent physicalism.

Recent imaging results suggest that individuals automatically share the emotions of others when exposed to their emotions. We question the assumption of the automaticity and propose a contextual approach, suggesting several modulatory factors that might influence empathic brain responses. Contextual appraisal could occur early in emotional cue evaluation, which then might or might not lead to an empathic brain response, or not until after an empathic brain response is automatically elicited. We propose two major roles for empathy; its epistemological role (...) is to provide information about the future actions of other people, and important environmental properties. Its social role is to serve as the origin of the motivation for cooperative and prosocial behavior, as well as help for effective social communication. (shrink)

Motivated by the seeming structure of the sciences, metaphysical emergence combines broadly synchronic dependence coupled with some degree of ontological and causal autonomy. Reflecting the diverse, frequently incompatible interpretations of the notions of dependence and autonomy, however, accounts of emergence diverge into a bewildering variety. Here I argue that much of this apparent diversity is superficial. I first argue, by attention to the problem of higher-level causation, that two and only two strategies for addressing this problem accommodate the genuine emergence (...) of special science entities. These strategies in turn suggest two distinct schema for metaphysical emergence---'Weak' and 'Strong' emergence, respectively. Each schema imposes a condition on the powers of entities taken to be emergent: Strong emergence requires that higher-level features have more token powers than their dependence base features, whereas Weak emergence requires that higher-level features have a proper subset of the token powers of their dependence base features. Importantly, the notion of “power” at issue here is metaphysically neutral, primarily reflecting commitment just to the plausible thesis that what causes an entity may bring about are associated with how the entity is---that is, with its features.

One of the main strategies against conceivability arguments is the so-called phenomenal concept strategy, which aims to explain the epistemic gap between physical and phenomenal truths in terms of the special features of phenomenal concepts. Daniel Stoljar has recently argued that the phenomenal concept strategy has failed to provide a successful explanation of this epistemic gap. In this paper my aim is to defend the phenomenal concept strategy from his criticisms. I argue that Stoljar has misrepresented the resources of the (...) strategy, which can indeed accomplish the required explanatory task, once it is properly understood. (shrink)

In this paper I argue that Frank Jackson.

The phenomenal character of conscious experience has long been regarded as the major problem for physicalist accounts of consciousness. In recent years, defenders of physicalism have typically been relying on the so-called Phenomenal Concept Strategy to avoid dualism. In this paper, we argue with PCS that cognitive-physicalistic explanations can account for the peculiarities of phenomenal character. However, we think that the conceptual features PCS investigates are not the genuine causes of the special characteristics of phenomenal consciousness but only symptoms, which (...) can themselves be explained in terms of the features of the sensory-perceptual representations underlying conscious experiences, namely that some, but not all, of these states are representationally unstructured. (shrink)

In this paper I discuss, on behalf of the materialist, a consideration against the modal or conceivability argument against materialism which was first voiced in the third lecture of Naming and Necessity. This consideration is based on intertheoretic identities, statements in which both terms flanking the identity sign are theoretical. I argue that the defender of the conceivability argument has trouble to account for the appearance of contingency in those types of necessary identities. In fact, intertheoretic identities pose a formidable (...) dilemma for the defender of the modal argument and actually force the antimaterialist to say more about the semantics of theoretical terms than is implicit in standard discussions of the argument. I myself consider several options in this regard, the upshot being, however, that none of the alternative semantics for theoretical terms available to the antimaterialist is good enough to achieve the twofold aim which her modal argument requires, namely, to account for the a posteriori necessity of identities of this sort and, at the same time, to preserve her antimaterialist argument. Finally, in the last part of the paper, I argue that my defense of materialism can withstand some worries coming from David Chalmers’ recent views on a priori scrutability. (shrink)

I construct a tempting anti-physicalist argument, which sharpens an explanatory gap argument suggested by David Chalmers and Frank Jackson. The argument relies crucially on the premise that there is a deep epistemic asymmetry (which may be identified with the explanatory gap) between phenomenal truths and ordinary macroscopic truths. Many physicalists reject the argument by rejecting this premise. I argue that even if this premise is true, the anti-physicalist conclusion should be rejected, and I provide a detailed, physicalist-friendly explanation of the (...) relevant premise. Along the way, I sketch an account of a priori conceptual knowledge that is compatible with naturalistic accounts of intentionality. I conclude by noting that the resulting view is a version of the popular phenomenal concept strategy that avoids a potentially worrying dilemma facing earlier incarnations of this strategy. (shrink)

Theories that combine physicalism with phenomenal concepts abandon the phenomenal irrealism characteristic of 1950s physicalism, thereby leaving physicalists trying to reconcile themselves to concepts appropriate only to dualism. Physicalists should instead abandon phenomenal concepts and try to develop our concepts of conscious states. Employing an account of concepts as structured mental representations, and motivating a model of conceptual development with semantic externalist considerations, I suggest that phenomenal concepts misrepresent their referents, such that if our conception of consciousness incorporates them, it (...) needs development. I then argue that the ?phenomenal concept strategy? (PCS) of a purely cognitive account of the distinction between phenomenal and physical concepts combines physicalism with phenomenal concepts only by misrepresenting physical properties. This is because phenomenal concepts carry ontological commitment, and I present an argument to show the tension between this commitment and granting ontological authority to physical concepts only. In the final section, I show why phenomenal concepts are more ontologically committed than PCS theorists can allow, revive U.T. Place's notion of a ?phenomenological fallacy? to explain their enduring appeal, and then suggest some advantages of functional analyses of concepts of conscious states over the phenomenal alternative. (shrink)

According to Frank Jackson’s famous knowledge argument, Mary, a brilliant neuroscientist raised in a black and white room and bestowed with complete physical knowledge, cannot know certain truths about phenomenal experience. This claim about knowledge, in turn, implies that physicalism is false. I argue that the knowledge argument founders on a dilemma. Either (i) Mary cannot know the relevant experiential truths because of trivial obstacles that have no bearing on the truth of physicalism or (ii) once the obstacles have been (...) removed, Mary can know the relevant truths. If we give Mary the epistemological capabilities necessary to draw metaphysical conclusions about physicalism, she will, while trapped in the black and white room, be able to know every truth about phenomenal experience. (shrink)

I argue that an identity theorist can successfully resist a Kripkean modal argument by employing what I call a metaconceptual move. Furthermore, by showing how this move fails to apply straightforwardly to Chalmers' argument, I clarify the nature of the threat presented by Chalmers and how it differs from a Kripkean modal argument.

In this paper, I examine the relationship between physicalism and property dualism in the light of the dialectic between anti-physicalist arguments and physicalist responses. Upon rehearsing the moves of each side, it is hard not to notice that there is a puzzling symmetry between dualist attacks on physicalism and physicalist replies. Each position can be developed in a way to defend itself from attacks from the other position, and it seems that there are neither a priori nor a posteriori grounds (...) to choose between the two. I suggest that the reason for the intractability of the disagreement, perhaps surprisingly, is they are both true: physicalism and dualism are formulated in terms of different conceptual schemes, each involving basic metaphysical concepts such as possibility, necessity, law and property. My proposal is that this means that there is no real disagreement in fact; both schemes get at the same reality, in different ways. -/- . (shrink)

Robert Stalnaker has argued that mathematical information is information about the sentences and expressions of mathematics. I argue that this metalinguistic account is open to a variant of Alonzo Church's translation objection and that Stalnaker's attempt to get around this objection is not successful. If correct, this tells not only against Stalnaker's account of mathematical truths, but against any metalinguistic account of truths that are both necessary and informative.

According to a posteriori physicalism, phenomenal properties are physical properties, despite the unbridgeable cognitive gap that holds between phenomenal concepts and physical concepts. Current debates about a posteriori physicalism turn on what I call “the perspicuity principle”: it is impossible for a suitably astute cognizer to possess concepts of a certain sort—viz., narrow concepts—without being able to tell whether the referents of those concepts are the same or different. The perspicuity principle tends to strike a posteriori physicalists as implausibly rationalistic; (...) further, a posteriori physicalists maintain that even if the principle is applicable to many narrow concepts, phenomenal concepts have unique features that render them inferentially isolated from other narrow concepts ). I argue, on the contrary, that the case for the perspicuity principle is quite strong. Moreover, not only have versions of the PCS repeatedly failed, likely, all versions will, given the strange combination of lucidity and opacity that the PCS has to juggle. I conclude that a posteriori physicalists currently lack a principled objection to classic anti-physicalist arguments. (shrink)

This paper examines the concept of information in situation semantics. For this purpose the most fundamental principles of situation semantics are classified into three groups: principles of the more fundamental kind, principles related to regularity, and principles governing incremental information. Fodor’s well-known criticisms of situation semanticists’ concepts of information target the first group. Interestingly, situation semanticists have been anxious to articulate either the principles of the second group or the principles of the third group in order to meet these criticisms. (...) Based on these observations, I will launch a dilemma for situation semanticists. Either they fail to handle information about individuals or they fail to present any acceptable account of the laws of nature. Millikan’s version of situation semantics, I shall argue, is not the exception to the rule. (shrink)

The aim of this paper is to defend the causal efficacy of consciousness against two specters of epiphenomenalism. We argue that these challenges are best met, on the one hand, by rejecting all forms of consciousness-body dualism, and on the other, by adopting a dynamical systems approach to understanding the causal efficacy of conscious experience. We argue that this non-reductive identity theory provides the theoretical resources for reconciling the reality and efficacy of consciousness with the neurophysiology of the brain and (...) body.

Mental files serve as individual or singular concepts. Like singular terms in the language, they refer, or are supposed to refer. What they refer to is not determined by properties which the subject takes the referent to have (i.e. by the information stored in the file), but through relations to various entities in the environment in which the file fulfills its function. Files are based on acquaintance relations, and the function of the file is to store whatever information is made (...) available through the relations in question. I offer a typology of files. The most important distinction is between proto-files and conceptual files. In contrast to proto-files, conceptual files can host not only information derived through the specific relation on which the file is based, but also information about the same object gained in some other way. In this framework identity comes into the picture twice. (i) Identity is presupposed when two pieces of information occur in the same file. Such 'presumptions of identity' ground the linguistic phenomenon of de jure coreference, which takes place when two singular terms, or two occurrences of a singular term, are associated with the same file. (ii) Judgments of identity work by linking two distinct files, thereby enabling information to flow freely between them. This corresponds to de facto coreference. (Linking is not merging ; identity judgments have the effect of merging files only when the files belong to a very specific category, that of 'encyclopedia entries' -- a type of conceptual file based on a higher-order relation rather than on a specific acquaintance relation.) In the last part of the paper I will discuss, and attempt to rebut, two objections to the mental-file account. According to the first objection, the account is circular ; according to the second objection, de jure coreference cannot be accounted for it in terms of identity of the associated mental files because de jure coreference is not a transitive relation.
